Now Safiya and Amy try a homework problem. Consider an electron moving with a speed of 6.90 106 m/s at right angles to a constant magnetic field, with B = 1.7 T. What is the radius of the circular path of the electron? r = _________ m
5. Consider an object of mass m moving with constant speed v in a circle of radius r. What is the algebraic expression for the centripetal acceleration ac of the object in terms of its speed v and radius r? (Use any variable stated in this part.) ac =
A particle of mass m moves in a circle of radius R at a constant speed v, as shown below. The motion begins at point Q at time t = 0. Determine the angular momentum of the particle about the axis perpendicular to the page through point P as a function of time. (Use any variable or symbol stated above along with the following as necessary: t.)
2. An electron moves in a circle of radius r = 5.66 x 10-11 m with a speed 2.09 x 10 m/s. Treat the circular path as a current loop with a constant current equal to the ratio of the electrons charge magnitude to the period of the motion. If the circle lies in a uniform magnetic field of magnitude B = 6.39 mT, what is the maximum possible magnitude of the torque, T, produced on the loop by the...

3. An object moves at constant speed v in a circle of radius r. How many times greateriless is the acceleration (a) if v is doubled, (b) if r is doubled? What happens to the acceleration as r-oo? as r→0? Why can't a car turn a corner instantaneously (in no time)-how great would the acceleration have to be?
